Abstract: A ceramic electrode structure designed to have an enhanced construction, wherein an induction electrode has an area larger than that of a discharge electrode. A high square pulse voltage is applied to the enhanced ceramic electrode structure, thereby increasing an efficiency of ion generation and effectively restricting generation of ozone.

Abstract: Disclosed are a refrigerator equipped with an ion generator and a method for controlling the same, capable of maintaining the density of ozone, which is generated together with ions, to a level less than a predetermined level. The refrigerator and the method for controlling the same can adjust the density of ozone in the refrigerator without employing additional equipment or the control for the equipment such that the ozone is not harmful to a human body by incorporating an operational pattern of a damper operating according to the temperatures of both a freezing chamber and a refrigerating chamber with the operation of the ion generator in order to control the density of the ozone generated from the insides of plural storage rooms by the operation of the ion generator.

Abstract: A storage box with a thermoelement is disclosed. This storage box is operable in a frozen-storage mode operation, in addition to a cool-storage mode and a hot-storage mode. During a cool-storage mode operation of the storage box, the main compartment (14) is primarily cooled by a main thermoelement (20) to be kept at a low temperature. The temperature difference between the areas around the two junctions (61, 62) of the sub-thermoelement (60) of a sub-storage unit (50) installed within the main compartment (14) is sufficiently smaller than that between the areas around the two junctions of the main thermoelement irrespective of a consideration of an addition of heat produced from heat exchanging units provided at the two junctions of each thermoelement. The sub-thermoelement (60) is thus significantly improved in its cooling capacity. The temperature of the sub-compartment (52) of the sub-storage unit (50) is thus reduced lower than 0° C., and so the sub-compartment is kept in a frozen-storage mode.
